* avcodec/opus: Rename opus.c->opus_celt.c, opus_celt.c->opusdec_celt.cAndreas Rheinhardt2022-10-091-484/+0
| | | | | | | | | | Since commit 4fc2531fff112836026aad2bdaf128c9d15a72e3 opus.c contains only the celt stuff shared between decoder and encoder. meanwhile, opus_celt.c is decoder-only. So the new names reflect the actual content better than the current ones. Reviewed-by: Lynne <dev@lynne.ee> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec/opus_celt: Break cyclic inlusion of opus_celt.h<->opus_pvq.hAndreas Rheinhardt2022-10-051-0/+1
| | | | | | | | Simply don't include opus_pvq.h in opus_celt.h: The latter only uses pointers to CeltPVQ. Reviewed-by: Lynne <dev@lynne.ee> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec/opus: Move stuff shared by decoder and parser to a new fileAndreas Rheinhardt2022-10-051-442/+0
| | | | | | | | | | | | | | | | | opus.h (which is used by all the Opus code) currently includes several structures only used by the parser and the decoder; several elements of OpusContext are even only used by the decoder. This commit therefore moves the part of OpusContext that is shared between these two components (and used by ff_opus_parse_extradata()) out into a new structure and moves all the other accompanying structures and functions to a new header, opus_parse.h; the functions itself are also moved to a new file, opus_parse.c. (This also allows to remove several spurious dependencies of the Opus parser and encoder.) Reviewed-by: Lynne <dev@lynne.ee> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec/vorbis: Split data declarations out into new headerAndreas Rheinhardt2022-10-031-1/+1
| | | | | | | | | vorbis.h currently contains stuff only used by the native Vorbis codecs and some Vorbis tables, which are also used by Opus and libvorbis. Therefore split the data out into a header of its own. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec/opus: always use ambisonic layout for mapping family 2James Almer2022-03-201-14/+3
| | | | | | | | | | | No need to use a Custom layout when the non diegetic channels can be described as a standard mask. This fixes: 45684/clusterfuzz-testcase-minimized-ffmpeg_AV_CODEC_ID_LIBOPUS_fuzzer-5039410989629440 Signed-off-by: James Almer <jamrial@gmail.com>

| | | | | | | | | | | | | | | | | | | | | | The idea is to use ffmath.h for internal implementations of math functions. Currently, it is used for variants of libm functions, but is by no means limited to such things. Note that this is not exported; use lavu/mathematics for such purposes. Reviewed-by: Ronald S.
